This is a primate instinct shared with all the great apes (and many other animals, too). The origin of this reflex is to try to scare the threat away and to alert others to the danger to get help, etc. In modern human societies, we sometimes still scream even when these things are not possible or relevant (e.g. in a scary movie, on a roller coaster, etc.), so now the scream means simply, "I am afraid and/or surprised."

Jumping when scared is a natural reflex triggered by the body's fight-or-flight response. It's an evolutionary mechanism to help us quickly respond to potential threats by getting us ready to either flee or defend ourselves. The sudden jump allows for a quick burst of energy and prepares the muscles for action.

∙ 15y agoPeople scream because... when they are mad or scared, they feel like they can get all of their anger out when they scream. I personally think that you should just talk it out, but aparently not many people think so these days!

∙ 14y agoThe jump is just a reaction to the scary thoughts in your brain which travels to the nervous system and since it's such a powerful demand, the nervous system spazzes and it spreads throughout the whole body and completes with a jump. Also, some people just do it for attention.
